Olga Palagushkina, Larisa Nazarova, Larisa Frolova Trends in development of diatom flora from sub-recent lake sediments of the Lake Bolshoy Kharbey (Bolshezemelskaya tundra, Russia). |
| Аннотация |
We studied diatom assemblages of a proglacial arctic lake Bolshoy Kharbey (Bolshezemelskaya tundra, Russian Arctic) from a short sediments core covering last ca 200 years. In total, 121 taxa from 2 classes, 5 orders, 18 families, and 50 genera were identified. The diatom flora included species with mainly cosmopolitan distribution. Alkaliphilic benthic diatoms preferring standing - flowing waters, indifferent to salinity and moderate temperature conditions dominated the assemblages. Main changes in diatom assemblages took place at ca 1870 and 1980. After 1870, which can be attributed to the end of the Little Ice Age, the species richness rose, especially of planktonic centric and small penate diatoms. Rise of diatom diversity took place most probably in response to climate warming, related to it prolongation of the growing season and period of open water. A negative trend in the Evenness of the diatom assemblages during the last decades can be seen as an early-warning signal indicating a decrease of stability of the lake ecosystem. |
